Transport -------------------------------------------------------------------------
㩷
Take care of the following points for transporting the Vacuum Pump.
Caution
㩷
1. Take full care of fall and tumbling down during transportation. An
INJURY
is feared.
2.
Lift up the Vacuum Pump equipped with a hanger bolt always after getting rid of
loosening of the hanger bolt. But after mounting the Vacuum Pump on a machine, do
not lift up the entire machine using the mounted hanger bolt.
Verify the mass of motor based in the nameplate, package box, outline drawing,
catalog or the like before lifting it and do not lift any more mass than the rated load of
lifting tool. The gravity center of the Vacuum Pump is located at motor side, therefore,
the Vacuum Pump inclines to one side during lift-up.
Exert tension gradually on the wire and do not lift up suddenly.
This lift-up work may only be executed by the qualified workers. Do not stay under
the Vacuum Pump during the lifting work.
An
INJURY
or
FIRE
caused by
FALL
or
TUMBLING DOWN
is feared for all of these
cases
.
3.
Ambient temperature should be kept –20

during transportation.
Lifting method of the Vacuum Pump
Safekeeping ---------------------------------------------------------------------
Take care of following points for safekeeping the Vacuum Pump or suspending its operation for a long
period.
1. For safekeeping in the packed.
Keep the Vacuum Pump in an indoor dry place (Ambient temperature: -20
㷄
~+50
㷄
). Do not keep
it on such a place, as is exposed to water or dust, or with vibration, or place it on a bare ground
directly.
2. For keeping it in the installed condition.
㩷
(a) Cover the entire Vacuum Pump with a sheet for protecting it from invasion of moisture foreign
materials.
(b) Keep the Vacuum Pump with its hanger bolt mounted. If it is kept with the hanger bolt
dismounted, water may sometimes invade into through the screw hole.
(c) Run the Vacuum Pump for some minutes keeping it and every 3 months, for protecting the
bearings from rusting.
(d) If the operation of Vacuum Pump is suspended for a long period, measure the insulation
resistance of its winding every 6 months and verify that it is kept at higher than 1 M
ȍ
. If the
resistance is not higher then 1 M
ȍ
at normal temperature, such measures are required as to dry
the winding.
(e) Keep the Vacuum Pump in an indoor dry place (Ambient temperature: -20
㷄
~+50
㷄
).
1. Use one hanger bolt
